Cluasach O Failbhe

Irish - A sailor. He set out with Ceannai Fionn in the hope of finding the end of the sea. When the ship's anchor was held fast on the sea bottom, Cluasach dived to release it but instead entered a magical city below the waves, where he stayed with a beautiful maiden and was seen no more. In some lore, occasionally identified as Cluasach O Failbhe.
